Configurable HTCondor worker node image

This docker image provides a HTCondor worker node which is configurable using ansible. HTCondor itself is configured using condor_git_config. Currently this image supports HTCondor's pool password and token authentication.

In order to configure your worker node, you need to create a directory containing an yaml containing the supported ansible variables described below.

Variable Description
HTCONDOR_CONFIG_GIT_REPO URL pointing to the Git repository containing the HTCondor configuration
HTCONDOR_CONFIG_GIT_CACHE_PATH Cache path location on destination system (optional, default=/etc/condor/config.git)
GIT_USER Username to use when accessing the Git repository above
GIT_TOKEN Token/Password to use when accessing the Git repository above
CLOUD_SITE_ID We are using condor-git-config white listing to support multiple cloud sites
HTCONDOR_POOL_PASSWORD (Optional) Pool password to authenticate the worker node with the HTCondor cluster (optional base64 support for binary passwords)
HTCONDOR_TOKEN (Optional) Token to authenticate the worker node against the HTCondor cluster (optional base64 support for binary passwords)
HTCONDOR_TOKEN_PASSWORD (Optional) Token password to authenticate the HTCondor cluster against the worker node (optional base64 support for binary passwords)

Example configurations

Create a new config directory and add a new file secrets.yaml containing the following contents depending the authentication method you would like to use.

Enable token based authentication

HTCONDOR_CONFIG_GIT_REPO: "https://git.somewhere.org/configs.git"
GIT_USER: "CaptainGit"
GIT_TOKEN: "Don't tell you!"
CLOUD_SITE_ID: "BotNet"
HTCONDOR_TOKEN:
  BotNet: Test123456
HTCONDOR_TOKEN_PASSWORD:
  BotNet: Test123

Enable pool password authentication

HTCONDOR_CONFIG_GIT_REPO: "https://git.somewhere.org/configs.git"
GIT_USER: "CaptainGit"
GIT_TOKEN: "Don't tell you!"
CLOUD_SITE_ID: "BotNet"
HTCONDOR_POOL_PASSWORD: "TopSecret123456!"

How to start-up the worker node

The workernode can then be started and configured by bind mounting the config directory into /srv/config.

docker run -v $PWD/config:/srv/config htcondor-wn:latest

In case you want to use a read-only singularity container, you need to bind mount a local directory into /scratch as well.

singularity run --userns -B $PWD/config:/srv/config -B ${SOMELOCALDIR}:/scratch /cvmfs/unpacked.cern.ch/registry.hub.docker.com/matterminers/htcondor-wn\:latest

The HTCondor is started automatically and HTCondor is configured using ansible and the static configuration in your Git repository.
